< cpp‎ | ranges‎ | zip view‎ | iterator

friend constexpr void iter_swap( const /*iterator*/& x, const /*iterator*/& y ) noexcept(/* see below */) requires (std::indirectly_swappable<ranges::iterator_t< /*maybe-const*/<Const, Views>>> && ...); |  | (since C++23)

Performs ranges::iter_swap(std::get<i>(x.current_), std::get<i>(y.current_)) for every integer `i` in `[`​0​`,` sizeof...(Views)`)`, where `current_` denotes the underlying tuple-like object that holds iterators to elements of adapted views.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `zip_view::iterator<Const>` is an associated class of the arguments.

### Parameters

x, y | - | iterators to the elements to swap

### Return value

(none)

### Exceptions

`noexcept` specification:
noexcept(

(noexcept(ranges::iter_swap(
declval<const ranges::iterator_t</*maybe-const*/<Const, Views>>&>(),

declval<const ranges::iterator_t</*maybe-const*/<Const, Views>>&>())) &&...))
